Release Notes

leptos-rs/leptos (leptos)

v0.8.6

Compare Source

Just a patch release, mostly to support #[server] #[lazy] for lazy server functions.

Going forward, patch releases for various crates will have version numbers that are not coupled to one another, and will only be bumped when they've actually changed; so this release is 0.8.6 for leptos, leptos_macro, and server_fn_macro, but does not arbitrarily bump other packages that haven't changed.

See 0.8.5 for notes on WASM splitting.

v0.8.5: : WASM code splitting released!

Compare Source

This release includes WASM code-splitting/lazy-loading support, in tandem with the latest cargo-leptos release.

You can use the lazy_routes example to understand what this means!

Essentially, though, there are two patterns:

1. Use the #[lazy] macro to make any given function lazy
2. Use the #[lazy_route] to designate a route with a lazy-loaded view, which is loaded concurrently with the route's data

#[lazy] converts a (sync or async) function into a lazy-loaded async function

#[lazy]
fn deserialize_comments(data: &str) -> Vec<Comment> {
    serde_json::from_str(data).unwrap()
}

#[lazy_route] lets you split routes into a "data" half and a "view" half, which will be concurrently loaded by the router. This works with nested routing: so if you have ViewD and ViewE, then the router will concurrently load D's data, D's (lazy) view, E's data, and E's (lazy) view, before navigating to the page.

struct ViewD {
    data: Resource<Result<Vec<i32>, ServerFnError>>,
}

#[lazy_route]
impl LazyRoute for ViewD {
    fn data() -> Self {
        Self {
            data: Resource::new(|| (), |_| d_data()),
        }
    }

    fn view(this: Self) -> AnyView {
        let items = move || {
            Suspend::new(async move {
                this.data
                    .await
                    .unwrap_or_default()
                    .into_iter()
                    .map(|item| view! { <li>{item}</li> })
                    .collect::<Vec<_>>()
            })
        };
        view! {
            <p id="page">"View D"</p>
            <hr/>
            <Suspense fallback=|| view! { <p id="loading">"Loading..."</p> }>
                <ul>{items}</ul>
            </Suspense>
            <Outlet/>
        }
        .into_any()
    }
}

#[server]
async fn d_data() -> Result<Vec<i32>, ServerFnError> {
    tokio::time::sleep(std::time::Duration::from_millis(250)).await;
    Ok(vec![1, 1, 2, 3, 5, 8, 13])
}

Our whole July stream was dedicated to the topic, if you want more in depth discussion.
